The machine illustrated in the drawings is generally in the form of a punch press, where in a base 20 is supported upon legs 21 and having a frame extending upwardly therefrom, consisting of side uprights 22 and 23. A crank shaft 25 is ournaled in the uprights, with its crank portionf26 intermediate the same. A power driven Hy wheel'27 is rotatably mounted upon one end of the shaft 25, being operably eonnectible thereto in a common manner by a suitable normally open spring operated clutch mechanism f (not shown), but operable upon releasing a catch by the lowering of a rod 28 by means of the usual hand lever 29. A pitman 30 is rotatably mounted upon the crank portion 26, and is suitably secured to areciproca'tingrgate 31, which is guided in its reciprocating movements, by the cooperation of the guides 32 thereon, with guideways 33 formed upon the uprights 22 and 23. Rotation of the shaft 25 causes reciprocation of the gate 31 toward and from the base 2O in the usual manner. A disk 34 is mounted upon the other end of the shaft 25 and is disposed without the adjacent uprights 23. Intermediate the disk 34 and the adjacent upright, an eccentric portion 24 is formed upon the shaft 25.

A punch block 35 containing a suitable set ofpunches for fabricating a iin for a radiator unit of a tin and tube radiator is secured to the underside of the gate 31. The punches cooperate with a set of dies mounted in a die block 36, secured upon the bed or base 20. In this instance, sufficient punches and dies are provided so that three tins are fabricated simultaneously, the tins dropping, partly due to gravity, as soon as fabricated, through suitably formed openings 37 in the die block 36 into chutes 38. y

A coil or other source of supply of material 39, suitable for fins, is provided and mounted upon a bracket 40 at one sideof the machine. The material 39 is fed over the dies beneath the punch by means of a pair of feed rolls 4l disposed at the side of the machine opposite to the coil of material 39, and which operate to exert a pull upon the material. The upper `roll of the pair of rolls 41 is arranged lin bearings in such a manner that the same may be raised out of contact with the strip of material by the engagement of a lever 43 secured thereto, with an adjustable stud 44 mounted upon the gate 31. This rollv and the bearings, therethe gate 31 so as to allow the strip of material 39 to remain stationary during the intcrval that the punches and dies are operat- In this instance the strip of material is fed intermittently by the rolls 41, they being rotated intermittently by the cooperation of a ratchet and pawl mechanism 45, the ratchet wheel of which is secured to the lower roll which is geared to the upper roll by the gear train 46. The pawlmember of the mechanism 45 is operated by a rod 47 secured t-o a lever arm 48, mounted upon the end of a rock shaft 49, secured upon the upright 23. The rock shaft is rotated by a rod 50, secured at one end to an arm 51, secured upon the other end of shaft 49, and at the other end to a stud 52 eccentrically und adjustably mounted upon the outer face of the disk By proper adjustment of eccentricity between the stud 52 and the disk 34, the pawl and ratchet mechanism 45 will operate to feed the strip of material a suiiicient amount during the nonoperatin g stroke of the punches to present beneath the same a required amount of vmaterial from which to form a fin or lins.

Secured to the shaft of the upper roll of the feed rolls 41, is a pulley 53 which, by a belt connection with a pulley 54 drives a takeup device 55 upon lwhich the scrap stock, not used in making the fins, is collected.

Guided by the chutes 38, the tins are received in a rack 60, being collected, arranged 1n spaced relation relative to each other, and' retained therein, while a tube is vbeing forced therethrough. The rack 6() 'is provided with a series of vertically disposed pockets 61, which are of a depth and widthsubstantially equal to the corresponding dimensions of the fins, and which are spaced apart longitudinally with respectto the rack the desired amount at which the fin will be' disposed upon the tube. The rack is slidingly supported in a guide 62 by the cooperation of the dove-tailed shaped sides 63 thereof with corresponding grooves in the guide 62. The guide 62 is secured to the machine by means of brackets 58 and 59, and with the rack is disposed below the bed or base 20.- A toothed gear rack 64 is secured to the underside of the rack 60, with which a pinion 65 meshes.l and by the rotation thereof slides the rack 60 relatively to the guide 62. A pair of racks 64 and pinions 65 are provided in this instance.

At a plurality of points longitudinally of the rack,`there is provided means to raise the assembled fins and tubes therefrom. Suitable openings in the rack 60 allow an arm 66 of a member 67 to be raised into engagement with the bottom edge of the tins. In this instance, three of such arms 66 are provided upon each member 67. Secured to the lower surface of the `member 67 is a downwardly extending bracket 68 upon which is mounted a roller 69. In a slot 70 formed in the under surface of the rack 60 is a longitudinally slidable barv71. The bar 71 is provided with a series of camming surfaces 72formcd upon upwardly extending lugs 73 thereon. The

lll)

removal thereof by the opi cured to an end of the shaft 74. In this instance, one at each end `is provided each of which meshes with a pinion 77 securely mounted upon a shaft 78.- A pawl and ratchet wheel mechanism having the ratchet wheel 7 9' thereof secured upon the shaft 78, is provided to rotate the same by the action of the pawl 80 thereof. The pawl 80 is mounted upon'a rocking lever 81 pivoted upon the outer end of the shaft 78, and is suitably urged toward the ratchet wheel 79 by aspring in the usual manner. The rocking'lever m81 is operably connected to one end of a rocking arm 82, which is pivoted to theupright 23 at 83 by a rod 84. The other end of the arm 82 is secured to an eccentric ring 85 rotatably mounted upon the eccentric portion 24 of the crank shaft 25. 'A' locking pawl 86 is provided which is pivoted to the guide 62 at 87 and suitably urged toward the ratchet wheel 79 by spring means in the usual manner to engage the teeth thereof to prevent backward rotation thereof. The rotation of the eccentrie portion 24 will cause the rack.60-to intermittently feedin one direction while the ins are being fabricated. The "gearing ,above described is so proportioned that the rack 60 will be fed in this direction' in timed relation to the action of the punches and dies, whereby a pocket 61 will be presented directly beneath the corresponding chutef38 to receive a fin as soon as it is fabricated.

Means is provided to` insure a rapid movement of the fabricated fins toward the rack 60 and to prevent them from rebounding and interfering with the action', of the machine when the same is being rapidly operated. A

' tube 90 is provided and disposed in each chute l38. Openings 90a directed downwardly toward the rack are provided in the tube 90. A supply pipe 91, communicating with tubes 90, providesa passage for -compressed air.

when the same is used'. A -valve 92 controls the flow of the compressed air through pipe 91 and tube 90. The air then flows out of the openings 90a in a steady stream which engages the fins as they drop into the chute 38 and rapidly forces them downwardly toward the rack 60. An endopen-ing 90b in the tube 90'permits the flow of air to engage the lin as it enters a pocket 61 and prevents it rebounding therefrom. v

Alock bar 95 is connected tothe lower end of the clutch operating rodl28 and extends downwardly therefrom into a lock box 96 wherein it may vertically slide. At its lower end, the bar 95 is provided with locking notches 97 and 98, the notch 97 forming a downwardly directed shoulder 99, and the` notch 98 formingan upwardly directed shoulder 100. A horizontally slidable bar 101 is guided in a slot in the boX 96 and by a bracket 102. The bar 101 is provided at one end with an inwardly directed notch .engaging member 103, and with an outwardly directed extension v104. A coil spring 105 tends to urge the bar 101 to cause the member 103 to enter the notch 98 and engage the shoulder' 100 when the lock bar 95 is moved downwardly bythe handle 29. A lock bar retaining rod 106 isalso horizontally slidable inthe bracket 102 and in a portion of the box 96. The rodv 106 is provided with a notch engaging end 107 adapted to enter the notch 97 and by engagement with the shoulder 99 to retain the bar 95, and-through it the hand lever 29, and clutch mechanism, in clutch released position. The rod 106, inthis instance, is manually operable and provides an accessible means whereby the machine can be locked in non-operating position, so that the same will notbe inadvertently started. A gravity actuated catch 108 engages the rod 106 in a suitable recess 109, to retain the rod in locked position.

The bar 101 upon being moved into a position to release the member 103 from engagement with the shoulder 100, allows the lock bar 95 to move upwardly whereby-the clutch mechanism will be operated into its normal open position, and the fly wheel 27 will rotate idly without operating the machine. The bar 101 is connected to anl arm 110 of a rock- .ing sleeve 111, rotatably Ymounted upon a bracket 112, and having a downwardly projecting pawl 113 thereon. Rotation in one direction of the sleeve 111 to rock it, causes the arm`1l0 to slide the bar 101in a direct-ion whereby the member 103 is released from engagement with'the shoulder 100. A pawl engaging vlug 114 is mounted upon the rack 60, and disposed in proper position thereon tofengage the pawl 113 and thereby to rock the sleeve 111 when the rack is in a predetermined position of its `forward sliding movement.

,In timed relation' with the engagement of the pawl113 and the lug 114, a member 115 secured to the rack 60 engages a'lug 116 ses., cured to a slidable bar 117, mounted upon the guide 62. l The bar 117 is provided with pawl engaging members 118 and 119, which engage` ates a toothed clutch mechanism 121. This action connects a forwardly rotating power driven pulley 122, which is freely rotatable upon a hollow shaft 123, with the shaft, one portion of the clutch mechanism 121 being secured thereto and the other forming a part of thel pulley 122 (see Fig. 8). Movement of the hand lever slides a clutch operating rod 124 through the hollow shaft 123, and due to thev connection 125 between the rod 124 and the shidable clutch member, moves the same. A shifting sleeve 126 is likewise secured to the rod 124, and by means of arms 127 is connected to a transversely slidable control bar r128, which is slidably retained at the rear ofthe machine in bracketsf129. A gear 130 is keyed or otherwise secured to the hollow shaft 123 and is in mesh with an idler pinion 131, which in turn is in mesh with a gear 132, secured to shaft 74. Rotation of the hollow shaft 123 by pulley 122 will, therefore, feed the rack 60 forwardly in a continuous movement.

At a predetermined point in the continuous forward feed of the rack 60, it is again stoppeddue to the engagement of an adjustable stop member 133, with a lug 134, mounted upon`a bar 135, slidably mounted upon the guide 62. A cam lug 136 is positioned upon the bar to engage at a predetermined time an arm 137 of a bell crank, the other arm 13S of which is in engagement wit-ha stud 139 projecting from the control bar 128. lVhen the cam lug 136 engages the bell crank arm 137, the bell crank is rocked whereby the control bar 128 will be shifted, and by moving the shifting sleeve 126, will release th'e clutch mechanism 121, thereby interrupting the connection between the pulle 122 and the holT low shaft 123 to stop the orward feed of the rack 60.

A tube supporting mechanism is secured to the forward end of the guide 62, and which cooperates with the rack 60, and its associated parts during their forward sliding movements. A tube retaining and supporting rod 140 is slidably mounted in a block 141, which is slidably mounted upon a base 156.` The rod 140 is directed inwardly toward the forward end of the rack through a tubular member 142, from which it projects a sufficient amount to support a tube; and to space itl longitudinally from the block 141. The arrangement is such that a tube 143 may be slipped over the 'i projecting end and held thereby, extending along a longitudinally extending groove 144 in the rack 60.S The groove 144 provides clearance for a flange 145 about a central opening in the fin 146. as well as clearance for the disposition of the tube 143 in proper position to enter the opening in the fin 146. In this instance, three rods 14() are provided whereby three tubes 143 may' be supported in corresp'onding grooves 144 in the rack 60. The rod or rods 140 are secured at one end to a plate slotted portion of the rac t, so that the same j will be engaged thereby when the rack reaches a predetermined point in its forward movement. Upon-engagement of the rack 60 with the rod 149, the same ywith the plate 147 and the rod or rods 140 is forced forwardly where- Y by the projecting end of the rod 140 is withdrawn from the tube 143. A continued forward'feed of the rack 60 causes the forward end of the same to engage another rod 150 which extends through the block, with its forward end secured to a plate 151, which is urged into engagement with the forward surface of the block by a compression spring 152.

The rod 150 is provided with a camming notch 153, disposed within the block 141, the camming surface of which engages a member 154 of a pin tumbler mechanism. Another member 155 of this mechanism is vertically slidable in the supporting base 156, being urged upwardly by a spring 157, so as to retain'the joint between the two members 154 and 155 above the lower surface of the block 141, and above the upper surface of the base 156, so that the two parts, block 141, and base 156, are retained against relative movement. By aligning the joint between the members 154 and 155 with the joint between the surfaces ofthe blocl 141 and base 156, the block 141 is released and under the urge of the spring 148, will vbe pulled forwardly, the .spring 148 being under tension due to engagement of the rack 60 with the rod 149. This action causes the block and its associated parts to be removed from the immediate neighborhood of the rack whereby the fins and tubes in the rack "are free'to be raised therefrom without the possibility 'of being interfered with by any overhanging parts. In this instance, two rods 150 with their associated parts have been provided.

A rod is secured to the forward end of the bar 71, and projects forwardly from the forward end of the rack 60, beingslidable therethrough. During the last period of the forward feed of the rack 60, the rod 160 engages against the rear surface of the base 156 and is pressed inwardly. This action moves the bar 71 rearwardly, thereby causing the camming surfaces 72 to engage the rollers 69,

whereby the fin and tube raising means is voperated to raisethe same out of the rack 60, whereupon the operator may readily remove the same from the machine.

By proper manipulation of the hand lever 120, a clutch member 161 (see Fig. 8) is engaged with a cooperating clutch 4member 162 formed in a pulley 163, freely'rotatable upon the hollow shaft 123 to connect the same 4thereto. The rotation of the pulley 163 is the reverse of that of the pulley 4122, so that the rack 60 may now be moved continuously rearwardly toward its initial iin receiving position. As the rack 60 approaches its predetermined initial position, an adjustable stop member 164 engages the lug 134. on the bar 135 to f reset 1t into its other position, and a camming lug 165 secured to ltherack 60, engages a roller secured to a depending arm 166, forming part of .the control bar 128. The engagement of the lug 165 with the arm 166 shifts the shifting sleeve 126, and by it the clutch member 161, out of engagement with the cor responding part 162 to disengage the pulley 163 from the shaft 123 to stop further feed of the rack 60 in a rearward direction.

. As the rack 60 approaches its initial position, a rod 167 projecting from the rear end of the bar 71 and `through the corresponding end of thelrack 60, engages againstan adjustable stop member 168, secured to the rear end of the guide 62. The engagement of the rod 167 with the stop 168 presses in the rod l 167 and slides the bar 71 forwardly, whereby the iin and tube raising means `is lowered and the rack 60 is in condition to receive and collect fins from the fabricating means into all of its pockets 61 thereof.

The control bar 128 is provided with a notch I v170, into which a spring pressed pin 171 mounted upon the base 20 in a bracket 172 is adapted to seat. The notch 170 is located in proper position lengthwise of the bar 128 so that when the pin 171 is seated therein, both clutches will he in inoperative position. A

- neutral position of the control bar 128 is,

therefore, provided and the bar is retained `in such position against inadvertent movement in either direction, due to vibration or the like, bythe cooperation of the pin 171 and the notch 170. Y i

The operation of the machine although obvious from the above description of the cooperating parts thereof, generally is as follows. A supplynf iin material 39 together with a supply 0f tubes 143, is provided. The machine is set with the rack 60 positioned with its forward end below the dies and beneath the base v20. A tube 143 is placedupon the project-ing ends of each of the rods 140, and power is applied to the crank shaft 25.

As soon as rotation starts, the feed rolls 41 act upon the strip of material to feed it between the punches and dies, and the punches descend and fabricate fins 146. The fins drop through openings 37 in the die block and are rapidly forced through chutes 38 into 'the pockets 61, of the rack 60, by the compressed air blast from the openings 90a and 90b of the' operations of the cooperating machine elements, the movements of the racks and the fabricating ,means are automatically stopped.

The operator then manipulates the hand lever 120 lto provide. a continuous forward feed to the rack, which again advances toward the block 141 located at the forward end of the machine.

At a predetermined period in its forward movement, the rack by engagement with the rod 149 releases the tube supporting rods and withdraws them from the tubes. A further advance of the rack in the same direction releases the block 141 from the'base 156, as above described.' Substantially simultaneously with the forward movement of the block 141and release of the same from the base 156, the pin 16()L operates to cause the bar 71 to raise the assembled fins and tube from the yrack 60. Atthis period of the machine operation the feed of the rack is again automatically interrupted by the engagement of the lug 136 with the arm 137 of the bell crank, which operates the control bar 128 andreleases the clutch 121.

By manipulation of the the other direction, the rack is provided with power whereby it is moved rearwardly into itsv initial position below the dies for the reception of newly fabricated ns. As it nears the termination of its rearward feed the bar 71 is reset into its initial position, whereby the fin raising means is lowered and the rearward feed ofl the rack is interrupted by the engagement of lug 165 with the arm 166, which operates the control bar 128 to release the clutch partsv 161 and 162from engagement. At substantially the Sametime that the feed is interrupted the control bar 128 1s moved into its neutral position with the pm 171 seated in the notch v170. Manipulation of the-bar`117 to slide it rearwardly p ermits the engagement of pawls 80 and 86 wlth the ratchet wheel 79 whereby intermittent forward feed of the rack 60 may be obtained. By supplying additional tubes, the machine may be again operated to fabricate and to assemble ns thereon as above described.

Thestrip of n material 39 is arranged in the machine illustrated, so that it moves hand lever 12() in the rack 60, which in this instance, moves longitudinally with respect to the forward and rear portions of the machine. The movement of the control bar 128 is also transverse to the direction of movement of the rack and the movement of the pawl control bars and continuous rack feed control bar, are in the same direction as the rack in the machine illustrated. Although the direction of movement of the above parts has been described as illustrated, deviation therefrom is possible under certain conditions,
